I assumed you meant something like that. So you're just saying pay attention to the coffee before the machine?

my iroast2 finally quit on me after 3 years of almost weekly use. certainly got my money's worth. so i finally ordered the behmor 1600 and am looking forward to some complex roasts, quiet, and large batches. sweet!

ima a huge coffee lover and this thread has opened my eyes to alot of cool machines

I currently use a krups grind and brew coffee machine and love it

its so much better to freshly grind the coffee, for me it makes a huge diff

the behmor arrived today...complete with small grid drum, 8 lbs. of various origins, and a smile on me face. turning out to be a great, albeit expensive, month - new roaster, hf2, and new iphone. yay!

2 things coffee related:

1) got a 'bottomless' (nude, lol) portafilter holder and triple-shot basket:

drilled out ($10 charge, well worth it) the bottom of a brand new holder and it avoids the 'spout' that you often see on the portafilter assemblies. its somewhat for show but also lets you gauge when to 'stop the pull' (as it starts to 'go blonde' as they say).

2) I'm still making progress on my DIY pid controller (arduino chip to keep temperature spot-on). my test bed, reading an LM35 sensor chip, direct in volts (77.7C reads from that voltage, just shift the dot a few places).

eventually, there will be an LCD display, box, buttons and some custom software.

Our Behmor just arrived as well.
Firing it up now.

Well I hope there is no Fire....

Linux -- why do you need the arduino to control the grinder

the next stage is done:

its now reading the analog sensor - but still letting the mech sensor (t-stat) do the on/off switching of the heating element. once the PID code is integrated, THEN I'll have actual cpu-based therm control. right now, though, I'm at least getting accurate and repeatable temp readings and testing out my devel/debug environment.

update: first code-drop! it has a graphics strip-chart mode that updates every 10 seconds and shifts the graph upwards. a neat and perhaps useful effect.

cool! i've done about five batches so far. my latest profile was given to me by a member at the greencoffeebuying club: 15oz. of coffee, 1# start at P3 C with 8 + added. as soon as it starts, do 8 - . first crack starts around the 4 minute mark...and lasts for about a minute and a half. i start cool (and open the door) about 45 seconds after the end of first crack (and before second crack).

member kwkarth here also has a behmor...he may be able to give us more tips.
